OK, you won't be disapointed with the STS, its a real powerhouse :P Stock settings were all flush if i remember correctly.

Right, Breakin, You will probably find that the engine is set extremely rich from factory settings, and to get a good steady idle, a nice HOT plug will help quite a bit. With mine, i let it idle for 2 tanks at stock, and once started, it idles no problem. You will find though its so rich, that even at full throttle at factory settings will only move about 2-3 MPH, very slowly, and will be kicking out all sorts of crap outta the exhaust. Just lean it up a little tank by tank, just enough to get the car moving a bit quicker each ime, but not tooo much.

After around 6-7 tanks of leaning slightly, my engine was at a point were if i wanted i could begin to tune it, although it was still rich at this point. Just tune as any normal engine from here. I think in total from stock i have leaned the HSN around 2 Whole turns and the LSN around 3/4 of a turn. Its now a flying machine.

Also after breakin is complete, you are recomended to remove the shims, i removed them around tank 13, theres 3, 2 copper shims and a aluminium one, take out the copper ones, an leave the other one in. You will see the engine come to life around tank 20, it really loosens up, and is difficult to catch!

Hope this helps... :P

Does the spring on the throttle to the carb make a diifernce because its quite loose.

dunno mine's loose to but the carb is ok, although it might not be strong enough to close the carb,hense it still goin at no throttle?

Thats too high for that engine, run 17/47, it will have more top end and will help keep the nose down, although it will still wheelie with ease :lol: If you are gonna run a titanium spur, make sure you have a matched CB as well. :lol:

so if i use a titanium spur i will need a titanium cb.is it nesercery to use titanium,and if not what do i need to do to stop the gear from stripping?and is 18/47 any good because then i dont have to buy any thing.

18/47 will certainly be better than 18/52. Robinson racingdo some great cb/spur combos check them out, but i would also strengthen your drivetrain if you are gonna go down this route, at the end of the day, somethings gotta give, i'd rather it be a £3.50 bit of plastic.... :)
